It is nearly always invisible dangers which are most terrifying. (VII.84)

This second half of the Gallic Wars is much more exciting than the first. In the previous four books the Romans steamrollered over everyone they encountered in a rather monotonous way. Here they experience the catastrophic loss of an entire legion and then the fierce siege of Quintus Cicero’s camp, i.e. for the first time you feel the contingency and risk involved in the entire project. And both events are carefully crafted to feature dramatic episodes of a kind not found in the first four.

Book 5: The second rebellion

The book title was supplied by the editors of the Penguin edition and refers to the revolt of the Belgic tribes.

1 to 8: Illyricum and Gaulish rebels

At the end of each campaigning season in Gaul, Caesar spends the winter in Cisalpine Gaul attending to administration. He also visits the third province he’s in charge of, Illyricum. Here he stamped on the Pirustrae tribe who had allegedly been raiding over the border into Roman territory. Representatives of the tribe met him to tell him it wasn’t them, and delivered hostages as he demanded.

By this point we’re getting used to certain things.

1. This is a world made up of scores and scores of tribes who co-exist uneasily, continually liable to be invaded or go invading themselves.
2. Raiding other tribes’ territories seems to be a common occurrence so presumably is a standard way of making a living, acquiring land or loot.
3. Caesar has a standard methodology. Where possible, meet and threaten representatives of the erring tribe. If they persist in troubling the peace, attack and defeat them. Either way, you insist on them sending hostages to be kept as security against good behaviour.

This handful of options are repeated endlessly. In the spring Caesar returns to Gaul where he has to sort out the Treveri, a tribe living close to the Rhine whose leaders have failed to come to the annual conference of Gallic tribes. Turns out two rivals are vying for leadership, Caesar supports Cingetorix.

He rides on to Portus Itius, from where the invasion is to be launched. Tellingly, he takes leaders of most of the Gaulish tribes with him. The most dangerous of these is Dumnorix, ambitious leader of the Aedui. When Caesar insists he accompany him to Britain, Dumnorix begins spreading rumours to the other chiefs that they’ll all be killed in Britain. The sailing is delayed 4 weeks by a contrary wind, towards the end of which Dumnorix left the damp with some Aeduin cavalry. Caesar immediately delayed the sailing and sent troops to recapture Dumnorix, buy force if necessary. Dumnorix did indeed put up a fight, drew his sword and told his followers to protect him. So the Roman cavalry killed him. End of disruptive influence.

9 to 25: Second expedition to Britain

Caesar had ordered his troops over the winter to build a massive fleet eventually consisting of 600 troopships and 28 warships. He sets sail with five legions (about 25,000 soldiers) and 2,000 cavalry. Including private ships they hired, the Romans appeared over the horizon with 800 ships, an enormous force. No wonder the defending Britons decided to retire to higher ground.

They disembarked without event, set up a camp, then Caesar marched the majority 12 miles or so inland till they came to a Briton camp. The Seventh Legion stormed it and forced the Britons to flee but Caesar brought them back to work on the camp.

They set out again to confront the Britons but were informed of a large storms and when he returned Caesar saw it had damaged lots of boats. he drew them further up on the beach, ordered repairs made, sent orders to Titus Labienus back in Gaul to start building more.

He gives an overview of the British which is a bit random. He includes the plausible notion that the coastal areas have been settled by incomers from the continent with trivia such as, the natives think it wrong to eat of hare, fowl, and goose although it’s alright to keep for pastime or pleasure. He also makes the wildly inaccurate claim that the climate is more temperate than in Gaul, the cold seasons more moderate. I don’t think so.

He gives a wildly inaccurate description of the geography of Britain, making it out to be a huge triangular island off the west coast of France extending down to opposite Spain. It’s a great mystery how the Romans managed to conquer anywhere without decent maps.

He mentions that the British paint themselves with woad so have blue bodies. But then goes on to say they share wives between groups of ten or 12 men. This is the kind of wildly improbable legend that disfigures to much of the ostensibly ‘factual’ writing of the ancient world.

Back to the present, he describes a lightning British attack on the camp which takes them by surprise and causes casualties. The British fight well, making use of chariots and loose formations which replace each other ad lib.

Next day he sends legions foraging but once again the Britons attack in numbers. It’s hard fought but this time the legions turn them and chase. The Britons scatter and never again attack in such a unified way.

The Britons had united under the leadership of one chieftain, Cassivellaunus. He withdraws his forces north of the Thames which the Romans traverse and continue fighting, with Cassivellaunus hiding his chariots in the woods, till opportunities present for raids.

Envoys arrive from the Trinovantes. Their young leader Mandubracius had already crossed the Channel to seek Caesar’s protection after his father was killed by Cassivellaunus. Caesar demands from Mandubracius hostages and corn, but when these are brought, lets him go.

When other tribes see how fairly Mandubracius was treated, they send envoys seeking Caesar’s protection, being the Cenimagni, the Segontiaci, the Ancalites, the Bibroci and the Cassi. He learns that Cassivellaunus has retreated to famous stronghold built in a good defensive position. Caesar lays siege to it and storms it from its weakest side. Meanwhile Cassivellaunus had sent orders to four allied tribes to attack the Roman camp in Kent, but the Romans repel the attack, kill many attackers and capture a tribal leader.

Summer is nearly over and Caesar decides to return to Gaul. So while he was in the ascendent and the Britons demoralised, he demanded hostages and set an annual tribute for Cassivellaunus to pay Rome. And not to attack the British tribes which had allied with Rome. Then he marches the legions to the coast and into the ships and so back to Gaul.

Given the size of the invasion fleet (800 ships!) which indicated that it was a serious attempt to permanently conquer at least the southern part of Briton, you can’t help concluding the invasion – both the invasions – were a failure.

26 to 37: Revolt of Belgic tribes and massacre of the 7th Legion

Caesar distributes his legions and generals with various tribes. The Eburonians rebel and attack a Roman camp. Ambiorix tells the Romans that a Gaul-wide agreement has been made to launch a concerted attack on all the Roman forces and moreover a group of German mercenaries has crossed the Rhine. So he warns them to leave their camp and promises them safe passage through his territory.

The Romans are surprised but it makes sense that the Eburonians wouldn’t rebel on their own. So, what to do? Caesar gives a dramatic set piece debate among the two commanders, Lucius Aurunculeius Cotta who says stay put, and Quintus Titurius Sabinus who trusts Ambiorix and recommends that they leave (28 to 29).

Sabinus wins the argument and the legionaries are told to pack their most important belongings and set off. Catastrophe ensues. The Gauls wait till the legion has entered a deep narrow defile then bottles them up at either end and starts to massacre them. At one point Ambiorix asks the two Roman generals to a meeting. Cotta refuses to go but Sabinus leaves the fight to climb a hill and approach Ambiorix. He and his centurions are ordered to lay down their weapons, which they do. But as they approach Ambiorix they are surrounded and then killed. The Gauls raise a shout and fall on the remaining Romans with renewed fury. Cotta and most of the force are killed. The remnant make it back to the camp where, that night, seeing they are surrounded, they all commit suicide. A handful of survivors make it to Titus Atius Labienus’s camp to tell the story.

It is thought that some 6,000 legionaries died in this colossal blunder. The massacre happened at Atuatuca in modern Belgium.

38 to 58: Siege of Quintus Cicero

Emboldened, Ambiorix rallies allied Gaulish tribes, and led a ‘huge mass’ of the Eburones, the Nervii, the Aduatuci and their allies and dependents against the camp of Quintus Tullius Cicero. This was somewhere on the river Sambre and about 80 miles from the camp Caesar had made at Amiens. The Gauls made a surprise attack as the legionaries (as so often) were out gathering firewood etc, but they fought a fighting retreat back to the camp. This the Gauls surrounded and invested. They had with them defectors and Roman prisoners who showed them how to build the kind of siege towers and earthworks the Romans used, so these were built and turned against their inventors.

The Gauls called a parley and offered Cicero the same deal they’d offered Sabinus i.e. to lay down their arms and walk away in peace. But Cicero is not as foolish as Sabinus and makes a defiant reply, telling the Gauls that if they lay down their arms he will send to Caesar who will judge them for their rebellion. And so the siege continues. On the seventh day a fierce gale blows up and the Gauls shoot flaming arrows into the camp which burn down a lot of the huts.

Cicero sends a series of messengers to try and get through to Caesar, but all of them are caught and some of them tortured in view of the camp. Eventually a native Gaul makes it through the blockade and to Caesar’s camp, to whom the news of Cicero’s siege comes as a shock. He immediately sends a message to Marcus Licinius Crassus at his camp 24 miles away telling him to march to meet him. Same to Gaius Fabius and Labienus. Labienus writes back that the entire force of the Treveri were upon him and so, on balance, it was too risky for him to leave his camp. Caesar approves this decision and sets off with just two legions to raise the siege on Cicero’s camp.

By a series of forced marches Caesar quickly reaches Cicero’s camp and sends word through a native messenger that he is near. The Gauls lift the siege and turn their forces to face Caesar, some 60,000 warriors (49). Caesar has 7,000 men (49). With the enemy only 3 or so miles away Caesar orders the building of a camp, only smaller than usual, and instructs the soldiers to run around and given an air of panic and fear. This lures the Gauls out into the open and then up to this camp which they start besieging. But they had barely begun engaging when Caesar ordered his infantry to flood out by side gates and the cavalry to sally out and attack the flanks. Taken by surprise the Gauls fled and the Romans were able to cut them down.

Then he marches to relieve Cicero. He is astonished to see the size and number of siege engines the Gauls had built and then to discover that almost all the defenders had been wounded and fought bravely. He publicly congratulates Cicero and all his men, carefully speaking to individual centurions and tribunes to thank them. He addresses the disaster of the massacred legion and assures them it was down to Sabinus’s error, unlike the resolute leadership of their own Cicero.

Caesar’s victory goes some way to rallying the Romans and, more importantly, their Gaulish allies. But nonetheless the tribes are in a ferment, all sending each other messages discussing alliances and attacks. Caesar realises he must winter in Gaul to keep an eye on the situation. Caesar calls meetings with the heads of various tribes, partly by threats, partly by promises, keeps them peaceful. The Aedui and the Remi remain the staunchest allies.

But the Senones try to murder their king, Cavarinus, who had been friendly to the Romans. Indutiomarus leader of the Treveri is particularly rebellious. He sends messages to the German tribes across the Rhine enticing them to war with the Romans, but none sign up, replying that they’ve learned their lesson.

In Gaul Indutiomarus is more successful in recruiting a large force from miscellaneous tribes, attracting to his standard exiles and criminals, training them, procuring horses and so on. Once he feels strong enough he calls an armed convention of the Gaulish tribes at which he a) outlaws Cingetorix, his son-in‑law and rival for leadership of the Treveri; and b) declares his intention to rally the Senones, the Carnutes and several other tribes, to march through the lands of the Remi and laying them waste, before going on to attack the camp of Labienus.

Indutiomarus with his massed forces approaches and invests Labienus’ camp. The latter feigns timidity and reluctance, all the while awaiting his opportunity. He recruits cavalry from nearby friendly tribes and keeps them all hidden in the camp, while Indutiomarus and his men ride up to the walls, yell and jeer and throw spears and abuse the Romans. At the end of a day like this, the Gauls are turning to ride away, with a false sense of security, when suddenly from two gates Labienus launched forth all his cavalry. Anticipating the enemy would scatter in confusion, Labienus carefully instructed his men to resist attacking anyone else but all of them to find and kill Indutiomarus. He put a big price on his head and sure enough some of his soldiers intercepted Indutiomarus at the ford of a river, killed him, cut off his head and brought it back to Labienus.

When they learned this, all his allies among the Eburones and Nervii flee, talk of rebellion is dowsed down and that winter found Gaul quiet.

Book 6: (53 BC)

1 to 8: Further revolt in Gaul

Caesar tasks three generals with raising new recruits and asks Pompey to send him the legion he recently raised in north Italy. He hears news of northern tribes conspiring to rebel and so makes a lightning attack on the Nervii, capturing cattle, prisoners and ravaging the countryside. When he convokes the annual conference of Gaulish leaders, the Senones, Carnuti and Senones refuse to attend, indicating their hostility. Caesar marches quickly on the Senones forcing their leader, Accio, to back down and hand over hostages.

Then he marches into the country of the Menapii in the far north, burning farms and villages and taking cattle and prisoners till their leaders were forced to sue for peace and hand over hostages in the usual way.

Meanwhile the Treveri, led by relatives of Indutiomarus, had gathered a large force of infantry and cavalry to attack Labienus. Labienus feigned fear and then pretended to leave the camp, luring the Treveri across the river onto flat ground this side. Once they were over he inspired his soldiers to turn and fight them, trapped by the river. Much killing. The Treveri submitted and the Germans they’d invited to come join them decided to stay on the other side of the Rhine.

9 to 10: Caesar crosses the Rhine, retreat of the Suebi

Another Rhine crossing:

1. to punish the Germans who had sent the Treveri reinforcements
2. to prevent Ambiorix finding asylum there

The Ubii swear it wasn’t them and he spares them. Investigation suggests it was the Suebi. The Suebi gather their men at a stronghold and await. Caesar’s men quickly build another bridge and he crosses it.

11 to 20: Description of the Gauls

Digression on the nature of Gaulish society. How the advent of the Romans reordered things to bring the Aedui and Remi into prominence. The Gauls fought every year among themselves. The Druids practised human sacrifice, sometimes in wickerwork giants which they set on fire (16).

When the father of a house, who is of distinguished birth, has died, his relatives assemble, and if there be anything suspicious about his death they make inquisition of his wives as they would of slaves, and if discovery is made they put them to death with fire and all manner of excruciating tortures.

Their funerals, considering the civilisation of Gaul, are magnificent and expensive. They cast into the fire everything, even living creatures, which they believe to have been dear to the departed during life, and but a short time before the present age, only a generation since, slaves and dependents known to have been beloved by their lords used to be burnt with them at the conclusion of the funeral formalities. (VI.19)

21 to 28: Description of the Germans

More primitive. Fewer gods, they only worship things they can see like sun, moon and fire. Sex in young men is frowned upon for stunting their growth. Land is redistributed each year to stop them becoming to land-bound and also to enforce a sort of equality. Obsession with war. When a chief proclaims a war anyone who resiles is shunned. They lay waste the land around each tribe.

The Gauls used to be more warlike than the Germans and at points crossed the Rhine and conquered. But being closer to Roman territory they’ve got used to trading and fine products unlike the Germans who remain more isolated and warlike.

He gives one of those characteristically ludicrous descriptions of the natural world, imputing to the great forest of Hyrcania a massive extent (true enough) and a number of fantastical animals.

The Penguin editor suggests that this long digression about Gauls and Germans was placed her to distract from the fact that Caesar’s second incursion across the Rhine, like the first one, achieved little tangible result. When the Germans retreat into the forest, Caesar doesn’t have the provisions to follow them and so, er, retreats back over the bridge, destroying the German end and placing a watchtower and guards on the Gaulish side.

29 to 44: Caesar returns to Gaul

Right up in the north, against the Rhine, is the territory of the Eburones led by Ambiorix. Caesar marches against them, sending ahead Gaius Volcacius Tullus with the cavalry. These go very fast and surprise Ambiorix off his guard with only a few men. However these hold off the Romans while Ambiorix saddles up and flees into the forest. He sends out messages telling every man for himself and many flee and hide.

The Segni and Condrusi come to Caesar and plead that not all Germans in Gaul are conspiring. They aren’t and give hostages and make peace.

Caesar makes his base at Atuatuca, then divides his forces in three and takes his force to ravage the land of the Eburones. Germans across the Rhine hear that there’s a free-for-all and cross the river 30 miles downstream of Caesar’s base, to join in. But prisoners tell them the Romans base is at Atuatuca, full of loot and poorly defended.

Cicero had been left in Atuatuca and initially kept the men penned up in case of attack. But after a week the frustrated men need to get out and the troops need corn so Cicero lets a detachment go collect some, and another detachment take out the animals for exercise. Inevitably it’s at this moment that the Germans appear, mounting a fierce attack, causing chaos. While a fierce fight goes on at the gates of the camp, the detachments sent to fetch food – raw recruits and servants – fell into a panic. Experienced centurions helped them form and wedge shape and make it back to the camp, but another detachment initially took to a nearby hill, then changed its mind and came back down into the flatlands where it was destroyed.

Failing to break in the Germans break off the engagement and ride back to the Rhine. Hysteria grips the Roman camp and rumours spread that Caesar and the other legions have been wiped out, until Caesar himself returns and restores order.

The Penguin edition notes that Cicero clearly deserved a bollocking but Caesar treats him very gently, listing all the extenuating circumstances he can think of. This is because his brother, the orator Marcus Tullius Cicero, back in Rome, is still a political force who Caesar needs to keep onside.

This is reminiscent of the panic at Vesontio back in I.39. Caesar supervises widespread burning and ravaging of the country, with the deliberate intention of starving the inhabitants. An enquiry into the rebellion of the Senones and Carnutes concludes that it was instigated by Accio, who is executed in the traditional Roman manner i.e. scourged and hanged.

Penguin point out that by holding courts, judging and executing leaders like this Caesar was behaving like the governor of an accredited Roman province which Gaul very much was not. It was arrogant (and illegal) behaviour like this which raised so much opposition back in Rome.

Book 7: The rebellion of Vercingetorix (52 BC)

By far the longest book.

1 to 7: General conspiracy of the Gauls — Vercingetorix chosen as leader

The murder of Publius Clodius in January 52 BC led to increased political turbulence in Rome. The Gauls, hearing of this, took advantage to conspire to overthrow the invader and regain their liberty. The Carnutes lead the rebellion and sack the town of Cenabum, killing the knight Gaius Fufius Cita, in charge of managing trade.

This inspires the leader of the Arverni, far away in the south of free Gaul, abutting on the Roman Province, one Vercingetorix. Background to Vercingetorix, namely his father was at one point premier chieftain of all Gaul but was executed for seeking to be king. When Vercingetorix proclaims his ambition to kick out the Romans, his uncle and other chiefs expel him from their capital, Gergovia, but Vercingetorix takes to the road recruiting followers and building up a following. Eventually he returns to Gergovia, takes over his tribe and sends out messages for a major, allied rebellion. He enforces ferocious discipline on his recruits:

compelling waverers by severity of punishment. Indeed for the commission of a greater offence he put to death with fire and all manner of tortures; for a lesser case he sent a man home with his ears cut off or one eye gouged out, to point the moral to the rest and terrify others by the severity of the penalty.

In Italy Caesar hears of numerous tribes forming alliances constellated around Vercingetorix’s leadership. Vercingetorix moves his forces into the territory of the Bituriges.

8 to 14: Caesar moves suddenly against the Arverni

But Caesar surprises Vercingetorix by clearing the snow from a pass through the Cevennes and approaching him from an unexpected direction. He leaves Brutus in charge of his camp and makes a forced march to Vienne. He picks up two legions and marches in through the territory of the Aedui into that of the Lingones, where two legions were wintering. Hearing all this Vercingetorix returns to the country of the Bituriges, and from there heads to assault Gorgobina, a stronghold of the Boii.

This is the longest book of the 8 and is all like this, two leaders criss-crossing ancient Gaul, doing deals with, or being double crossed by, numerous tribes, sending out legions or detachments or squads of cavalry under lieutenants. The names of tribes and locations Caesar passes through, allies with or fights gets very confusing. In brief: Caesar takes three Gaulish towns, Vellaunodunum, Cenabum and Noviodunum.

15 to 31: Siege, defence, and capture of Avaricum

Vercingetorix had suffered 3 defeats in a row so holds a conference of his allies and persuades them to adopt a scorched earth strategy, withdrawing before the Romans and destroying all towns, villages, fields and crops in their paths, with a view to starving them. But the Bituriges went down on their knees and begged him not to burn Avaricum, their fairest town.

So Vercingetorix relents, but Caesar besieges it, for 25 days building an elaborate rampart wall and two huge siege towers. When the population of the town tries to sneak out one night, Caesar takes it, puts it to flame and massacres the 40,000 inhabitants.

Caesar adjudicates leadership contest between rival leaders of the Aedui. But the one he chooses betrays him, a week later telling his people that the Romans have massacred their army, so they have no choice but to go join Vercingetorix and fight for freedom.

34 to 53: Siege of Gergovia

The chief oppidum (fortified town) of the Arverni.— abandoned, after severe repulse. Impulsiveness of the troops who do not hear the recall, continue up the hill to storm the stronghold but are repulsed when the enemy muster with overwhelming numbers. — 46 centurions 700 men

This was the one and only military defeat Caesar suffered at the hands of the Gauls in 8 years. Caesar gives speech reprimanding men and insisting on discipline and then withdraws from Gergovia, marching back along then crossing the river Allier.

54 to 57: Caesar moves against the Aedui.

58 to 62: Labienus, successful against the Parisii, joins him.

63 to 74: General revolt of the Gauls under Vercingetorix.

They attack Caesar, but are defeated, not least because of Caesar’s German cavalry, and retire to Alesia, a town of the Mandubii. Caesar leaves two legions to guard his baggage and swiftly pursues Vercingetorix, killing 3,000 of his rearguard. Three Aeduin traitors are brought to Caesar.

68 to 89: The siege of Alesia

The Gauls retreat inside this stronghold. Caesar orders his troops to construct massive siege-works eleven miles in length, featuring 11 camps and 23 forts. After a confused fight between the opposing cavalries, Vercingetorix adopts the following strategy: he orders his cavalry to leave in the dead of night from a gate which isn’t yet covered by the Roman siegeworks, and to ride to their respective tribes and to raise all men of military age and bring them back, all in the name of a Final Battle which will achieve National Liberation. Meanwhile, all grain is confiscated and Vercingetorix adopts a daily ration for his 80,000 men, which should last a month or so of siege, until the reinforcements from the tribes arrive.

Details of Caesar’s astonishingly complex and thorough siegeworks which face both in and out.

Schematic side view of the Roman siege works at Alesia, 52 BC

The Gauls hold a national convention at which the tribes allot armed forces to send to Alesia, with various factions resiling and bickering. Eventually an astonishing force of 260,000 sets off, but by this stage Alesia’s food supplies have run out.

Caesar describes a meeting of the leaders inside Alesia and gives a speech – presumably entirely fictional – to Critognatus, a noble Avernian who, after a long prologue, recommends cannibalism (77)! It is also notable as belonging to that genre of speeches which Roman authors attributed to their enemies, in which the enemy eloquently describes the crushing servitude and slavery imposed by the Romans.

The weak and old and wives and children are expelled from Alesia and trek over to the Romans to beg them for food. But the Romans barely have enough to feed themselves and refuse the refugees food or permission to pass. So they are caught in no man’s land to starve.

The Gaulish hoard arrives, much to the joy of the besieged who throng the barricades to watch the battle. Caesar places all his infantry around the 11 mile siegeworks then sends his cavalry against the Gaulish cavalry. The Romans suffer casualties before an attack by German cavalry breaks the Gauls and chases them back to their main camp.

A day later a co-ordinated attack from the relieving force triggers a sortie by the besieged and the Romans find themselves hard pressed. But they are defeated by the Romans firing from their strong defences, and fall into the complex web of trenches, booby traps filled with spiked poles and so on. They are forced to withdraw while the besieged are still trying to fill in the first trench of the inner siegeworks, so the latter retreat back into the town, too.

The Gauls then mount an attack on the one Roman camp which isn’t integrated into their defensive circuit, while the besieged again sally forth. (The complexity of the siegeworks and the peril and anxiety of the repeated attacks remind me of the atmosphere at another famous French siege, Dien Bien Phu in French Indo-China, March to May 1954.)

Caesar sends Labienus with reinforcements to the hilltop camp, sends Brutus with reinforcements to the strongest point of the sallying army, then leads reinforcements in person. The forces attacking the hilltop hesitate, then Labienus sallies forth with the cohorts he had picked up. Caught between these cohorts and Caesar’s cavalry, the Gauls panic, break ranks and are slaughtered.

Sedulius, commander and chief of the Lemovices, was killed; Vercassivellaunus the Arvernian was captured alive in the rout; seventy-four war‑standards were brought in to Caesar; of the vast host few returned safe to camp.

Vercingetorix conceded defeat to the tribal leaders inside Alesia. Kill him or surrender him alive, as they wish. The leaders go under flag of truce to Caesar, who sits in front of his fortifications. Vercingetorix is handed over, all the chiefs lay down their arms. Caesar puts the Aeduin and Arvernian prisoners to one side to use as bargaining chips with their tribes, then distributes all the captures Gauls to his army as loot, one Gaul to one Roman.

(I think what this means is each Roman soldier then gets his prisoner to contact his family and demands a ransom for their safe return. So equivalent to cash.)

Caesar then receives the submission of all the tribes, and carefully allots legions and commanders in the territories of the main tribes for the winter. When news of this comprehensive victory reaches Rome, a public thanksgiving of twenty days was granted.

Book 8

This final book was not written by Caesar but by his lieutenant Aulus Hirtius. He was a legate of Caesar’s army of Gaul from 58, and crossed the Rubicon with him in January 49. He fought for Caesar during the civil war, and was appointed governor of Transalpine Gaul in 45. In other words a senior figure.

Preface

Hirtius addresses his friend Lucius Cornelius Balbus, another friend of Caesar’s, serving under him as chief engineer (praefectus fabrum) in Gaul. Balbus was said to have attended the very select dinner Caesar hosted, along with Sallust, Hirtius, Oppius and Sulpicus Rufus on the evening of the day when he crossed the Rubicon.

He explains to Balbus that he is continuing the Commentaries because they don’t link up with Caesar’s own account of the Civil; War. He says he has finished the third of the latter books, set in Alexandria, and has now set to filling the blank between book 7 and the outbreak of civil war by supplying a book 8. But it has been hard work to match Caesar’s clear elegant style and also the speed and alacrity with which he wrote.

1 to 48: (51 BC) End of the revolt in Gaul

Winter of 52 to 51 Caesar hears that the Gauls are plotting again. Alesia proves they cannot defeat the Romans when the latter’s forces are united, but might be able to pick off the legions scattered around the country in different tribal regions.

At the end of December Caesar set out on a lightning march and caught the Bituriges in the fields (it’s not actually likely they would be tilling their fields in the depths of winter, is it? Is this a stock literary convention of this genre?) Anyway, Caesar captures thousands but then lets them go and, when they see him being similarly merciful to nearby allied tribes, the Bitiruges decide to submit and give hostages.

Carnutes dispersed, Bellovaci defeated. Dumnacus besieges Lemonum, but without success. The Armoric states subdued. Drappes captured. Uxellodunum besieged and taken by Caesar. Exemplary punishment, the captured have their right hands chopped off. Labienus’ successful operations against the Treveri. Commius subdued.

49 to 55: (50 BC) Caesar and the Senate

Caesar’s triumphal reception by cities and colonies. He returns to the army in Gaul. A description of his opponents in the Senate. Caesar returns to Italy.

Thoughts

Political consequences

1. Caesar’s Gallic Wars were fought to a) clear his debts b) bring him glory and political power.

2. But in doing so he went far beyond his brief as proconsul – dealing with the leaders of free Gaul as if he was governor of a conquered province, invading Britain (twice) and crossing the Rhine, far exceeding his authority. This prompted growing criticism in Rome throughout his eight-year command. And it was this which created the mounting political crisis about whether he would ever be prepared to lay down his command and return to Rome as a normal citizen – the ultimate result being that he was too scared to do so and, instead, crossed the Rubicon into Italy with his army thus triggering five years or ruinous civil war

The war itself

1. Interesting to learn how universal the exchange of hostages was – the standard procedure to ensure peace, not only with the Romans but among the Gaulish tribes themselves.

2. The relentless Roman victories of the first four books get a bit boring. Book 5 is far more dramatic and exciting, when the massacre of Sabinus’ legion and the siege of Quintus Cicero for the first time introduce a real sense of risk and uncertainty and pave the way for the epic account of the struggle against Vercingetorix in book 7.

3. The invasion of England cost a huge amount of time and money and resources and, in the end, seems completely futile. He took away hostages from southern tribes but, presumably that lapsed when Caesar returned to Rome a few years later. Nowhere was settled, no bases or camps, no trading. Seems like an expensive folly.

Anti-imperialism

One of the interesting things about the text is the way it contains its own anti-argument. Caesar’s entire account takes it for granted that rule by Rome is best for the Gauls. And yet fairly regularly he puts into the mouths of Gaulish leaders as direct speech, or attributes to them in indirect description, the wish to be free men in their own land, living under their own laws.

It’s not an unreasonable wish. And every time you read it, you think, ‘Just what right did Caesar think he had to ravage, burn, pillage, and endlessly fight all these peoples?’ Maybe he thought he was bringing ‘peace’ to a territory plagued by endless internecine violence but it’s hard to see how the endless campaigning and fighting and burning and selling into slavery which the Romans brought was an improvement. It consistently feels worse.

Slavery

Interesting when one of the chiefs, Ambiorix, complains that hostages given by his family were being treated ‘like slaves’ and put in chains (V.27). And, of Gaul in general:

Throughout Gaul there are two classes of persons of definite account and dignity. As for the common folk, they are treated almost as slaves, venturing naught of themselves, never taken into counsel. The more part of them, oppressed as they are either by debt, or by the heavy weight of tribute, or by the wrongdoing of the more powerful men, commit themselves in slavery to the nobles, who have, in fact, the same rights over them as masters over slaves. (VI.13)

At numerous other towns the inhabitants were captured and sold into slavery. But then so were some the captured Romans. Caesar says Britain is famous for half a dozen exports to the continent, among which are slaves.

In other words, slavery was current throughout Gaul, Britain and the land of the Germans, so well beyond ancient Greece or Rome. Was there any part of the known world where slavery wasn’t practised two thousand years ago? Was slavery universal?

Eternal war

The Gauls fought among themselves every year. The Britons fought among themselves until Caesar’s incursion temporarily united them. The Germans lived for war. The Italians went on aggressive campaigns every year and spent half their time fighting each other. In Africa Jugurtha, in Asia Mithridates and the Parthians, in Egypt civil war. War everywhere, every year, all the time, forever.

The stupidity of war

Men fighting, I get. It’s what we do, what we’ve always done. But some incidents highlight the sheer brainless stupidity of war and the terrible, futile, stupid cost to civilian victims, women and children. The height of lunacy is reached in book 7 when Vercingetorix persuades the Averni, to burn down their own towns and destroy their own crops all in the name of freedom and victory. Reminiscent of General Westmoreland’s famous quote during the Vietnam War, that the Americans had to destroy the village in order to ‘save’ it. Or Vladimir Putin’s determination to ‘save’ eastern Ukraine by utterly devastating it.

War crimes

In descriptions of other Roman campaigns I’ve wondered whether what the Romans did amounted to war crimes. Yes, is the short answer. Massacring the populations of entire towns, including women and children, is a war crime.

Caesar’s sustained eight year campaign of destroying towns, massacring their inhabitants or sending them off into slavery, have caused many moderns to compare his actions as a genocide. If a genocide is defined as the systematic attempt to wipe out a particular ethnic group, then no, he just wanted every tribe in Gaul to submit, not to exterminate them.

On the other hand, when tribes or towns did hold out, it appears, from his often very casual references, that he did consciously raze towns to the ground and either massacre or enslave entire populations, most notably at the town of Avaricum, and then at Uxellodunum (VIII.44). Or:

Caesar thought that the next best way of obtaining the satisfaction that his honour demanded was to strip the country of inhabitants, cattle and buildings so thoroughly that any of the Eburones who had the good fortune to escape would loathe Ambiorix for bringing such calamities upon them and never allow him to return. Detachments of legionary or auxiliary troops went all over the country killing or capturing large numbers of the natives, burning the homesteads, and carrying off plunder, until it was completely devastated. (VIII.25)

There’s a revealing moment early in book 8 when Hirtius mentions that the population of the Carnutes are still living in makeshift tents and shacks, as all the towns in their territory have been razed to the ground (VIII.5).

At moments like this you see a vast landscape where all the towns, villages, fields and crops have been destroyed, leaving the survivors to scrape a living in pathetic shelters beside burned-out fields, and you realise this is what the Romans meant when they said they brought ‘peace’.

The scarlet cloak

Caesar always wore the scarlet cloak (paludamentum) of a commander-in‑chief (VII.88).
